#include <stdio.h>
#include <stdlib.h>

int main() {
unsigned char a=100,b=50;

printf("%d & %d = %d\n",a,b,a&b);
printf("%d | %d = %d\n",a,b,a|b);
printf("%d ^ %d = %d\n",a,b,a^b);
printf(" ~%d = %d\n",a, ~a);       /*the out come of this  line would be this: ~100 = -101 */
printf(" %d >> 2= %d\n",a, a>>2);
printf(" %d << 2= %d\n",a, a<<2);
system("pause");
return 0;
}

/结果应该是 155，不是吗？/
